What Is Mechanical-Heat-Recovery?
Mechanical-heat-recovery is a system that harnesses the heat energy in your home and uses it to reduce your energy consumption and costs. It works by extracting warm air from kitchens, bathrooms, and utility rooms and transferring the heat to fresh air from outside. This ensures your home is properly ventilated while retaining as much heat as possible. The heart of the mechanical-heat-recovery system is the heat-recovery unit.
This unit is typically installed in a central location, such as the attic or basement, and is connected to ductwork throughout the house. It consists of a heat exchanger that allows the outgoing, warm air and the incoming fresh air to pass close to each other without mixing. As the warm air transfers heat to the fresh air, the heat exchanger ensures that the two air streams do not mix, preventing cross-contamination.
How Does A Heat Recovery Unit Work?
A heat-recovery unit is the heart of a mechanical-heat-recovery system. The unsung hero quietly works behind the scenes to save you money on your energy bills. But how does it work? Well, let’s break it down. The heat recovery unit is typically installed in a central location in your home, like the attic or basement.
It’s connected to a network of ductwork that runs throughout the house. Inside the unit, there’s a heat exchanger, essentially a barrier that allows the outgoing, warm air and incoming fresh air to pass close to each other without mixing. Here’s how it works: when warm air is extracted from areas like the kitchen, bathroom, or utility room, it passes through the heat exchanger.
At the same time, fresh air from outside is drawn into the unit. Heat is transferred from the warm air to the fresh air without mixing as the warm air passes by the cold incoming air. This means that the outgoing stale air is expelled outside while the incoming fresh air is warmed up by the heat recovered from the exhaust air.
